Question

simplify the following expression (8-√7) (7-3√3)​

Answer 1

       $\underline{\bold{Answer:}}$

       $56-24\sqrt3-7\sqrt7-3\sqrt21$

       $\underline{\bold{Step-by-step-explaination:}}$

       $\text{The given expression is }(8 - \sqrt7)(7-3\sqrt3)$

       $\text{Simplifying the expression}$

$\implies \boxed{8(7-3\sqrt3)-\sqrt7(7-3\sqrt3)}$

       $\text{Simplifying the expression}$

$\implies \boxed{8(7)-8(3\sqrt3)-\sqrt7(7)-\sqrt7(3\sqrt3)}$

       $\text{Simplifying the expression}$

$\implies \boxed{56-24\sqrt3-7\sqrt7-3\sqrt21}$
